Security documents (currency, treasury bills, stocks, bonds, birth certificates, etc.) provide an interesting problem space for investigating information hiding. Recent advances in the quality of consumer printers and scanners have allowed the application of traditional information hiding techniques to printed materials. This paper explores how some of those techniques might be used to address the problem of counterfeiting as the capability of home printers to produce “exact” copies improves.
